Williams is also being rememberd on iTunes, which has set up a "Remembering Robin WIlliams" section that includes over 40 of his movies and stand up comedy shows.

iTunes has divided Williams' work into "Essentials," "Comedy" and "Drama," and also posted a photo of him with the following paragraph on his illustrious career.

"One of the most beloved and unforgettable performers in the history of show business, Robin Williams brought laughter and inspiration to millions. Throughout a career that spanned five decades, Williams evolved from stand up comedian to international movie star. Among the great masters of improv, he transfixed audiences with a mile-a-minute comic energy. Williams' Golden Globe-winning turn in Good Morning, Vietnam demonstrated that his versatile acting talents were equally suited to evoking dramatic complexity. Many of Williams' most iconic performances--in Dead Poets Society, Mrs. Doubtfire, and his Oscar-winning triumph Good Will Hunting--were dazzling high-wire acts that left audiences in tears of laughter one minute and tears of poignancy the next."

MacRumors reminds us that a speech by WIlliams' character, Professor John Keating, in the movie Dead Poets Society, was the inspiration behind Apple's "Your Verse" line of iPad advertisements. Keating delivered the famous "What will your verse be?" line in the movie. Williams was also the voice over in this iPad Air commercial, one of his final productions.
